Time-lapse Photography

Language	English

Objective Use the key to set the time delay and take pictures with SONY camera after the setting. Principle Here we can set the time delay by detecting how many times you press the key and use the infrared transmission sensor to control SONY camera. Equipment Module Number Function Microduino-CoreUSB 1 Core board Microduino-Sensorhub 1 Sensor pin board Microduino-IR transmitter 1 Infrared transmission sensor Microduino-Crash 1 Crash sensor 文件:IR Crash.jpg 600px Hardware Buildup Setup 1：Stack CoreUSB and Sensorhub together.。 文件:CoreUSB Sensorhub.jpg 600px Setup 2：Connect the infrared transmitter to the D8 pin of Sensorhub and the crash sensor to the D2 pin of Sensorhub. 文件:Ir transmitter.jpg 600px Software Debugging Infrared remote control encoding definition. Here we adopt SONY encoding format. #define PHOTO 0xB4B8F //SONY camera ending #define KEY 2 //Key interface boolean keyFlag = false; //Key flag unsigned long timeFlag = 0; //Time flag int delayTime = 0; IRsend irsend; 文件:Microduino photo ir.png 300px Judge how many time you press the key. If you can't detect the next press-down within one second of the last press-down, it means you've finished pressing down. Then, after delaying for a certain period of time, it'll send photo encoding and control the camera to take photos. if((millis()> timeFlag+1000)&&delayTime>0) // Judge how many time you press the key. If you can't detect the next press-down within one second of the last press-down, it means you've finished pressing down. { delay(delayTime*1000); //Set the delay time according to how many times you press down. for (int i = 0; i < 3; i++) { irsend.sendSony(PHOTO, 20); //Send photographing instruction delay(10); } Serial.println("take photo"); delayTime = 0; } if(keyFlag==false && digitalRead(KEY)==LOW) //Judge if the key is pressed down. { keyFlag = true; } else if(keyFlag==true && digitalRead(KEY)==HIGH) //Judge if the key is released. { delayTime++; //The time of pressing the key+1 timeFlag = millis(); keyFlag=false; } delay(100); Program [MicroduinoDelayPhoto] Result Align the infrared transmission sensor to the infrared receiving head of the camera, set remote control mode, press the key for several times and then take pictures after a while.
